Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that the existing methods for preventing and controlling plant diseases, insect pests and weeds spend a lot of manpower and material resources on the treatment of large-scale outbreaks of plant diseases, insect pests and weeds. The root cause can only be controlled to a certain extent, and it will recur when the conditions are met. A large number of pesticides also cause far-reaching and lasting harm to humans and the natural environment. A device for preventing and controlling plant diseases and insect pests with ozone and its disinfection method are provided

specific Embodiment approach 3

[0015] Specific implementation mode three: (see figure 2 ) This embodiment is used for the disinfection of plants and soil in plastic greenhouses or greenhouses. Irrigation device 11 is arranged in plastic greenhouses or greenhouses 12. Ultraviolet lamps 13 and ozone concentration sensors 14 are also provided in plastic greenhouses or greenhouses 12. Or the bottom of greenhouse 12 is also provided with the exhaust ventilation fan 15 that communicates with plastic greenhouse or greenhouse 12 inside and outside. When the ozone concentration sensor 14 of the present embodiment detects that the ozone concentration exceeds the standard, the ultraviolet lamp 13 is automatically or manually turned on to decompose the ozone gas, and the exhaust ventilation fan 15 can also be turned on to reduce the ozone concentration or stop the work of the ozone generating system, and wait for the ozone concentration to decrease. When it is below the warning line, turn on the ozone disinfection sys...

Abstract

The present invention discloses a device utilizing ozone to control plant diseases and pests and disinfection methods thereof, which relate to a device used to control plant diseases and pests and disinfection methods thereof. The purpose of the present invention is to resolve the problems that a large quantity of manpower and material resources need to be involved in the prior control of plant diseases and pests, and a great deal of agricultural chemical brings about significant and persistent harm on the human being and the natural environment. One end of a first pipeline of the device is communicated with the outlet of an ozone generator, and the other end of a second pipeline is communicated with a sprinkling irrigator. In the first method, the concentration of the ozone in ozone water is between 1mg / l and 10mg / l, and 45 tons to 55 tons of the ozone water is flooded in each mu of land. In the second method, 4 tons to 6 tons of the ozone water is flooded in each mu of land, and the concentration of the ozone in the air is controlled less than 1mg / l. The device adopts the ozone generator to produce ozone gas, which is turned into ozone water by a gas-liquid mixing device to disinfect the soil, part of the unresolved ozone enters into an irrigation system along with the ozone water, thereby, the air is disinfected, and plants are washed and disinfected.

Description

technical field [0001] The invention relates to a device for preventing and controlling plant diseases and insect pests and a disinfection method thereof. Background technique [0002] Crop diseases and insect pests are one of the main natural disasters faced by human beings. It has the characteristics of various types, great impact and frequent outbreaks. The loss of fruit trees and vegetables due to pests and diseases is about 15-20% in the world every year. Since the 1950s in my country, the occurrence area of ​​major crop diseases and insect pests has been increasing, especially since the early 1970s, the occurrence area and frequency of diseases and insect pests have increased year by year, which has become the main restrictive factor for the development of high-yield, high-quality, and efficient agriculture in my country. [0003] At present, chemical pesticides are mainly used to control pest disasters. Due to the long-term and large-scale use of pesticides, the air...
